What must a soldier do to request a transfer after receiving a letter of acceptance?

To request a transfer after receiving a letter of acceptance, obtaining a release from the losing commander is essential because it ensures that the current unit is officially aware of and supports the soldier's decision to transfer. This step is crucial as the losing commander holds the authority to release the soldier, which facilitates a smooth transition to the new unit. The release validates that all obligations and responsibilities to the current unit have been addressed, thus preventing any potential administrative issues during the transfer process.

Proper protocols must be followed to maintain operational integrity and readiness within both the losing and gaining units. This release serves as an important administrative component to the transfer request, ensuring that it aligns with the overall personnel management practices within the military.
